2 Claims.

This invention relates to a gem setting and has for one of its objects to provide an arrangement whereby an inexpensive setting may be obtained which will accommodate gems of widely varying shapes and sizes.

A more specific object of the invention is to provide a gem setting which will have the gernengaging arm designed to be coiled, possibly through more than one convolution, so that with a tight rolling of the coil a small gem may be accommodated, or with a looser rolling of the coil, a larger size gem may be accommodated.

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. l is a top plan view of a gem setting with the gem mounted in the setting.

Fig. 2 is a sectional View on line 2--2 of the structure of Fig. 1.

Fig. 3 is a sectional View on line 3-3 of Fig. 1.

Fig. 4 is a top plan view of a blank which has been slit, but before the gem-engaging fingers have been rolled into place.

Fig. 5 is a top plan view of a modified form of setting with the gem mounted therein.

Fig. 6 is a sectional view of the structure shown in Fig. 5.

Fig. 7 illustrates the same setting but with a different shaped stone than that shown in Figs. 5 and 6 mounted therein.

Fig. 8 is a sectional view of the structure shown in Fig. 7.

Fig. 9 is a sectional view illustrating in full lines the gem mounted in position and in dotted lines a larger gem mounted in position on the same setting.

Fig. 10 is a top plan view of a still different arrangement of the setting involving the same invention.

Gem settings usually employ some sort of finger or raised portion of stock which is deflected over the edges of the gem to hold the same in position. Such settings are usually of rather limited capacity so far as varying size gems are concerned, although the long prong finger type of crown setting permits of some bending of the fingers for the accommodation of various sizes. However, in order to increase the range of setting, both from the standpoint of capability of taking difierent shapes of stones, as well as different diameter or size stones, I have provided rolled fingers located in spaced relation so that should a square or some stone having corners be provided, the corners may extend between the fingers and I coil the engaging fingers inwardly so that the outer surface of the coil will engage the gem, but the coiling of the fingers enables a large variety of diameters of gems to be accom- 5 modated inasmuch as when the coil is opened a larger gem may be inserted, whereas when the coil is tightly rolled, a much smaller size gem will be accommodated; and the following is a more detailed description of the present embodiment of 10 this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, ll! designates generally a blank of sheet stock which is split as 15 at H and it to provide the fingers l3 and intermediate portions l4. These fingers l3 are rolled inwardly as illustrated at l5, (see Figs. such as 2 and 6) so as to engage a stone or gem H whichrests upon the base l8 flat upon this middle sur- 20 face, while the portions It are bent to flare on the opposite direction to provide an ornamental border. The gem I1 is of a mound type shape and generally tapered so that its under surface which engages the base H] is its largest diameter. 25 Thus when the fingers l3 are rolled inwardly so as to contact the surface of the gem, they will extend over a portion of the gem and hold the same firmly against the base.

These fingers ii are placed at intervals so as 30 to provide somewhat of a rosette as seen in Figs.

1 to 4 inclusive or they may be spaced even further apart as illustrated in Figs. 5, 6, 7 and 8. In this last group of figures mentioned, a gem such as is illustrated at i9 may set upon the base i8 35 and the plurality of fingers, 4 in number, rolled inwardly to engage this gem. The gem in this instance, i9, is circular, but the same base 20, which is circular, may also accommodate a gem 2i square in shape with its corners 22 extending 0 outwardly between the fingers It.

In Fig. 9, the base H3 is illustrated as accommodating a mound-shaped stone 23 with its fingers rolled inwardly to contact the surface of the stone. These fingers are coiled rather tightly 5 as shown in Fig. 9, but if a larger stone is desired to be accommodated, such as shown in dotted line, at 24, these fingers will be unrolled, as illustrated in dotted line at 25, and then this larger sized gem will be accommodated and held against 50 the base in a like manner.

In Fig. 10 a round gem having three fingers I3 is provided and illustrating another variation and ornamental shaping which may be formed.

In each instance the outside surface of the coiled finger engages the gem for holding the same in position.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible.

I claim:

1. In a gem setting, a base upon which an upwardly tapered gem is designed to rest, a plurality of fingers spaced about the periphery of the gem and extending outwardly and upwardly from the base, said fingers being rolled inwardly in a coil, each finger of which springs directly from the base with the inner circumferential surface of the coil engaging the gem and extending over a portion of the gem to hold the same in position against the base.

2. In a gem setting, a base upon which the gem is designed to rest, a plurality of spaced fingers extending outwardly and upwardly from the base, said fingers being rolled inwardly in a coil, each finger of which springs directly from the base with the inner circumferential surface of the coil engaging the gem to hold the same in position against said base, said coil of the fingers being variable in amount of roll to vary the size of the gem accommodated on said base.
